Quantum Optics with Quantum Dot Spins

Abstract

Self-assembled semiconductor quantum dots (QDs) have atom-like properties such as discrete energy levels coupled by optical transitions and their coherence properties can be revealed in quantum-optics experiments. Further, the availability of these transitions are governed by spin-dependent optical selection rules. This opens a channel to control and detect a single spin in a quantum dot via lasers. However, QDs can also interact strongly with a spin (nuclei) and/or a charge (electrons) reservoir of the solid-state environment leading to a rich source of interaction mechanisms. Consequently, identifying the regimes of these mechanisms is crucial for achieving a level of control in solid-state-based systems similar to that of atoms. I will provide a highlight of recent progress on all-optical control of quantum dot spins.
